One-Tier jar high-Capacity Laboratory jar Mill; 13" Roller, 115 VAC/60 Hz

These laboratory mills incorporate all-welded steel frames, powerful roller chain drives, and pillow blocks with cartridge-type permanently sealed ball bearings for efficient operation. Totally enclosed 1/4-hp DC motors and solid-state controls permit variable roller speed selection from 20 to 300 rpm for grinding a variety of wet and dry materials. The long-wearing, chemical-resistant rollers are self-centering and resistant to static buildup. Rollers easily adjust to accommodate a variety of jar diameters-no clamping or fastening required. Choose a mill with either one or two tiers from the table below. One-tier mill 04149-10 accepts two or three jars at one time-grinds twice the amount of the other one-tier mills. Two-tier mills rotate several jars at one time and save horizontal space. Each tier accepts jars measuring from 2" (5.1 cm) to 10" (25.4 cm) in diameter. What's Included: the 115 VAC models include cord with standard plug; the 230 VAC model includes cord only. Mills require milling jars and grinding media; order separately on right.
